Principally a pine forest on shallow soil over glacial stoney rubble. Mostly ~50 year old tree. Just few older. The trail rounds the small shallow lake mostly above. Petty views of that water. At the highest point a short detour to the west reveals an excellent vista. Pine forests, in my opinion, are a bit dull. The Fells are popular, this trail is less crowded than others.

Decent walk around the reservoir. It was a bit more challenging than I expected it to be. The trails were a bit hard to find at times but course correction wasn't difficult to get back on track. Parking is limited so get there early.

Hiked this today- great hike with some parts being more access-road-like and others being wooded trails. Part of the trail is the Rock Circuit trail which can be lots of rock climbing up/down which was difficult for a beginner like me, but a good challenge.

One great view of Boston after a quick rock scramble. Otherwise the hike was wooded with a few small ponds. I skipped several sections of the trail due to time constraints and lack of interest in climbing all the little rocks. I also skipped the beginning/end because I parked at the ice rink parking lot. Difficult to follow the mapped out loop because the blazes change and many offshoots aren't clearly marked. Could hear road noise for over half the hike. Took me about 2 hours.

We locked our bikes up near Gate 12, and started the hike from the south. Some parts of the trail are well marked with orange/red markers, other parts were a little harder to follow. The trail had some moderate parts that had some inclines and rocks, but it was overall easy-moderate. Surprisingly, the trail doesn't hug super close to the reservoirs, so you don't have water views most of the time. It was very nice though; it took us 2.75 hours at a regular pace.

A pleasant hike/walk. Well paved trail. We walked during most of the trail. There are frequent ups and downs. An easy hike. Pack a book, you'll find plenty of scenic sports to stop, picnic, relax and read a book.
